The challenge

Although tanks were equipped with an Automated Tank Gauging System, our customer's standards in compliance with the latest recommendations from API (API2350 4th ed.) required an independent high-level alarm system to prevent overfilling, separate from any device and method used for ATG.

Specifications required SIL3 level switches according to IEC61508, IEC 61511-1/ certified by TŰV, based on the vibrating fork principal, and continuously self-monitoring.

Application details

The Overfill Prevention System in compliance the latest API 2350 standards, is a modular SIL3 solution for level monitoring and alarming in case of detected risk of overfill. In case of any error or alarm, visible and audible notifications are activated and the related messages are shown on the display and on cabinet with the possibility to have more details about the failures.

Detailed engineering and factory acceptance tests

Detailed engineering July 2012: Once the order was accepted, the detail design was completed to include instrumentation design, cabinet, cabling, excavation and project documentation.

Factory acceptance tests: Key components of the project including instrumentation and the cabinet passed the FAT prior to installation to confirm their compliance with the specifications. By mid-November 2012, all components were shipped and the installation work started.

Site installation and site acceptance test

Site installation: All involved personnel went through the customer's safety training. Method Statements, Risk Assessments and Work Permits were issued prior any work to be carried out onsite. Site installation was completed on time according to all customer's safety procedures.

Site Acceptance Test: In December 2012, all site work was completed. The system was inspected and verified based on the customer's standard functional test. Personnel training and hand over followed.
